Intel’s 16th Gen Panther Lake Embraces LLVM/Clang with AVX 10.1-512 ISA Integration

Intel's 16th Gen Panther Lake processors will use LLVM/Clang, support AVX 10.1-512 ISA, and include Cougar Cove architecture, with desktop and notebook versions expected in late 2025.

Support for LLVM/Clang 18.1
Inclusion of AVX10.1-256 and AVX10.1-512 instruction set architecture
Possible 16 cores, including 4P, 8E, and 4 LPE cores

Intel’s 16th Gen Panther Lake processors are set to embrace LLVM/Clang with AVX 10.1-512 ISA integration, according to the latest update. This means that the upcoming processors will be supported by LLVM/Clang 18.1, and will feature the AVX10.1-256 and AVX10.1-512 instruction set architecture. However, it’s important to note that the AVX10 ISA will not be included in this lineup, as it will be exclusive to the Granite Rapids processors and their successors.

The 16th Gen Panther Lake processors, also known as the Core Ultra 3 series CPUs, are expected to succeed the 15th Gen Arrow Lake or a possible Arrow Lake Refresh. These new processors will first make their debut in the notebook segment before being released for desktops. The LGA1851 socket will be retained for the desktop and DIY markets once it launches.

In terms of architecture, the Panther Lake processors will feature an upgraded P-core architecture called Cougar Cove. The Skymont E-core, on the other hand, will be retained with minor changes. The compute tile will be fabricated on the 18A process node, indicating that it is likely to be a mobile family of processors. Rumors suggest that Panther Lake will have 16 cores, including 4P, 8E, and 4 LPE cores.

Notebook processors based on Panther Lake are expected to arrive in late 2025. Meanwhile, Clearwater Forest, which is the Xeon E-core equivalent of Panther Lake, will succeed Sierra Forest around the same time. Clearwater Forest is expected to feature up to 288 cores based on the Darkmont architecture, which is essentially a repurposed Skymont architecture designed for cloud applications. It will compete against the successor of AMD’s EPYC Bergamo processors, which will be based on Zen 5c and fabricated on a TSMC 3nm node with 256 or more cores.

While these details provide an exciting glimpse into Intel’s future processor lineup, it’s important to note that they are based on rumors and speculation. As always, it’s best to wait for official announcements and benchmarks to get a clearer picture of the performance and capabilities of these processors.
